RERAILING-FEOG.

To all whom it may concern:

Be it known that I, WALTER MARTLEY, a citizen of the United States ofAmerica, and resident of Lebanon, in the county of Laclede and State ofMissouri, have invented certain new and useful Improvements inRerailing-Frogs, of which the following is a specification.

This invention relates to rerailing frogs and more especially to thatclass of frogs in which two similar devices are provided, each of whichis adapted to be used in conjunction with the other and to be applied torailroad ties in such manner as to guide the wheels of a car truck backon to the tracks.

When a car or locomotive is derailed some of the wheels are forcedoutside of the tracks while the other wheels restupon the ties betweenthe tracks. For this reason the frogs provided for guiding the wheelsback to the tracks must be of two. different types, one adapted toreceive the tread of the wheels which remain between the tracks andguide the same to position and the other adapted to receive such wheeland lift the same over the tread of the rail in orderthat the flange mayrest in its proper position within such rail.

It is well known that similar devices have been constructed but it isnotorious that the large majority of them have faults which heretoforehave not been overcome. Most of them are heavy and take up considerableroom and are not easily transportable while others cost a great deal tomanufacture and are objectionable from that standpoint. None of them areabsolutely efficient nor are they simple.

It is the object of applicants invention to overcome these disadvantagesand to provide a rerailing device which will be simply and easilyconstructed at a low cost and which will be as eflicient as the moreexpensive devices now in use.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification, wherein likecharacters denote corresponding parts in the several views, in which-Figure 1 illustrates a view in elevation Specification of LettersPatent.

from the front or operative end showing the two frogs comprising myinvention in po sition; Fig. 2 illustrates a plan view of the same; andFig. 3 illustrates a longitudinal section on the line XY of Fig. 1.

In carrying my invention into practice, it is necessary, as pointed outbefore, to provide two frogs of slightly different construction, thesefrogs being shown at A and B in the figures. The frog A is adapted to beattached to the ties upon the inner side of the rail or in other words,between the two rails. In this way it is adapted to guide back to therails the wheel which is positioned between the said rails. This frog isprovided with a substantially level surface 3, also a sloping surface 4,which terminates near its upper end in a substantially level surface 5which is adapted to throw the tread of the wheel on to the tread surfaceof the track 2 and to guide the wheel flange into position. Disposedalong the inner edge of the base 1 and extending along the inclinedsurface t is a guide rail 6 which approaches the rail 2 at an angle.This guide rail may be of angular formation as shown or it may becurved, the object being to prevent the wheel from sliding off of theinclined surface i back on to the ties. It will be observed that theguide rail 6 terminates slightly short of the rail 2 in order to permitthe wheel flange to roll off of the substantially level surface 5 intoposition against the inner surface of the rail 2.

Pivoted at 8 near the junction of the inclined surface 4 and the surface5 is a shiftable track member 7 pointing downwardly and having its lowerend tapered. When the wheel approaches the surface 4, the shiftabletrack member 7 is adapted so that its tapered end will receive the treadsurface of the wheel and guide it upward to the plane surface or plate.In this way, I am able to adjust my device so as to allow for slightvariations in the direction of approach of the wheels, and the levelsurface is adapted to retain the wheel at rest while this shiftablemember is being adjusted in position to receive the wheels.

The frog B is adapted to be placed along the outside of the rail; thatis between the rail and the ends of the ties. This frog is of similarconstruction to frog A, a difference being that the plate 5 of thelatter is on a somewhat higher plane than the track surface of the railand has an extension 9, overlying the track surface and flush with theinner vertical surface of the rail head, said extension having a convextaper toward its edge and constituting a slideway for the flange of thewheel in being replaced on the track. The car wheel is guided to thisslideway by the shiftable track member 7, upon which it rides to theconvex member overlying the rail, from the convex surface of which theflange slides, thus seating the tread of the wheel upon the overlyingplate. The wheel now being alined with the track, it is only necessaryto roll it until it descends from the end of the overlying plate to thetrack and the operation is completed.

It will be understood that the frogs described above may be connected tothe rails or to the ties in any suitable manner but I have shown in thedrawings a series of spikes or feet 11, projecting from the under sidesof said frogs, which spikes are forced into the ties 1 by the weight ofthe car upon the bases 3. Recesses 10 may be formed along along thelower inner edges of the bases 3, said recesses being adapted to receivethe base flanges of the rail 2 in order that the frogs may set closelyagainst the rails. It will be understood, however, that these are simplydetails of construction which may be varied at will and I desire it tobe understood that the construction above set forth may be varied withinthe scope of the appended claims.

I claim 1. In a re-railing frog, a base comprising a sloping surface anda substantially level surface, said sloping surface being intermediatethe ends of said base and having pivoted thereon a shiftable trackmember, and a guide rail crossing the base diagonally.

2. In a re-railing frog, a base comprising substantially level surfacesand a sloping surface intermediate the level surfaces, a shiftable trackmember on the sloping surface adapted to receive the tread of a carwheel and bear it to the upper level surface, a guide rail diagonallycrossing the base and a slide-way comprising an extension of last saidlevel surface, said slide-way overlying the top surface of the rail andits edge being flush with the inner vertical surface of the rail head.

3. In a re-railing frog, a base comprising substantially level surfaces,a sloping surface connecting said level surfaces, a shiftable trackmember pivoted on said sloping surface, a bent guide rail diagonallyspanning the base, and adapted to direct the flange of the wheel to theslide-way, said slide-way comprising an extension of the upper levelsurface and adapted to overlie the rail tread and direct the wheelflange thereto.

In testimony whereof, I have hereunto afiixed my signature in thepresence of two witnesses.
